PROPAGATION OF MAGMA-FILLED CRACKS

This review begins by highlighting the observations of ancient and modern dikes that lay the groundwork for current modeling. The emphasis then shifts to the dominant physical processes involved - host rock fracture and deformation (elastic and inelastic), magma flow, and heat transfer. This review attempts to provide a framework for thinking about important but poorly understood processes such as dike initiation, the role of dike propagation in the ascent of granitic magmas, and earthquakes accompanying magma transport. -from Author
